This is a package for discrete choice model estimation and simulation, with an emphasis on large choice sets and behavioral refinements to multinomial models. Most of these models are not available in Statsmodels or Scikit-learn.

The underlying estimation routines come from two main places: (1) the urbanchoice codebase, which has been moved into ChoiceModels, and (2) Timothy Brathwaite’s PyLogit package, which handles more flexible model specifications.
